The greenhouse effect caused by the increase of atmospheric CO

2

concentration has become a global issue. CO

2

molecule has strong stability

and the traditional pyrolysis method has certain limitations in transforming CO

2

. Application of plasma technology for recycling CO

2

resource has exhibited good prospect. We briefly introduced the basic principle and advantages of CO

2

conversion by plasma and discussed the role of the catalyst in the conversion process. Moreover

we summarized the recent（past five years）researches at home and abroad on dielectric barrier discharge（DBD）

sliding arc discharge and microwave discharge plasma to convert CO

2

as well as the studies of the combination of DBD

microwave discharge and diffe

rent catalysts. Based on the current research status

the problems and challenges of plasma-converted CO

2

technology were analyzed. It was proposed to use plasma technology to combine CO

2

with co-hydrogen reactants to produce energy-efficient products

and to balance the CO

2

conversion rate and energy efficiency in the future. The direction of development in the future was expected.
